Harmonics up to the 18th order are generated from solid targets by focusing 2mJ2mJ, 50fs50fs pulses at 800nm800nm to a spot size of 1.7μm1.7μm (FWHM). To our knowledge, this is the first demonstration of high-harmonic generation with a very short focal length paraboloid (푓/1.4f/1.4) and kilohertz laser system. The harmonics have a low divergence (<4°<4°) compared to the driving beam and conversion efficiencies (>10−7>10−7 per harmonic) comparable to gas harmonics. No contrast enhancement techniques are employed, and the system is capable of operating at 500Hz500Hz.
